Difluorocarbene is the
chemical compound with
formula CF2. It has a
short half-life, 0.5 and 20 ms, in
solution and in the gas phase, respectively. Although...
-
involves pyrolysis to give
difluorocarbene,
which dimerizes: 2 CHClF2 → C2F4 + 2 HCl The
compound also
yields difluorocarbene upon
treatment with strong...
-
unstable even at low temperatures. It
degrades to
lithium fluoride and
difluorocarbene.
Trifluoromethyl copper(I)
reagents are more useful.
These reagents...

white solid, is of
interest as a
source of
difluorocarbene: CF2ClCO2Na → NaCl + CF2 + CO2 This

- is
difluorocarbene, CF2,
which is a
singlet whereas carbene (CH2) has a
triplet ground state. This
difference is
significant because difluorocarbene is...
- dimerization). An
exception are
dihalocarbenes such as
dichlorocarbene or
difluorocarbene,
which are
reasonably stable and will
react to form
geminal dihalo-cyclopropanes...
- The
technical synthesis is by the
reaction of
cyclopentadiene with
difluorocarbene. The
initially formed cyclopropane undergoes a ring
expansion and subsequent...
- not
isolable and
rapidly decomposes to
yield lithium fluoride and
difluorocarbene. Ruppert, Ingo; Schlich, Klaus; Volbach,
Wolfgang (1984). "Fluorinated...

Decarboxylation of
sodium chlorodifluoroacetate generates difluorocarbene: CF2ClCO2Na → NaCl + CF2 + CO2
Decarboxylations are an
